Probabilistic Model on Methyl Mercury Intake

Rice, Hammitt, and Evans publish results from a probabilistic model describing the possible monetary benefits of reducing methyl mercury. The article, published in Environmental Science & Technology (volume 44, issue 13) estimates an additional $860 million with a 10% reduction in exposure to the US population.


Welcome to the Environmental Health Simulation Page

This section is an extension and complement to exposurescience.org and is meant as a space for researchers developing, using, and generally interested in simulations applied to environmental health and exposure science. Theoretical concepts in statistics, stochastic processes, computational methods, and modeling frameworks are all topics of interest, as are applications of simulations in environmental health, human exposure assessment and analysis, pharmacokinetics, health risk, and environmental science.

Saving Data with the Sidepak Built-In Logger

In this video, I demonstrate how to set the TSI Sidepak AM510 aerosol monitor to automatically save data in its internal memory.

  1. Turn on the Sidepak by pressing the pink "Page" button on the far left of the front control panel
  2. Wait for the Sidepak to enter in Survey Model
  3. Press the "Page" button again to enter the MAIN MENU
  4. Press the down arrow key until you see Setup and the press the Enter key
  5. Page down until you see the Logging Interval submenue
  6. Press Enter and set the new logging interval using the arrow keys

Performing Zero Calibration on the Sidepak

In this video, I demonstrate how to zero calibrate the TSI Sidepak (AM510) aerosol monitor:

  1. Make sure the Sidepak is turned on by pressing the leftmost pink button "Page"
  2. Once the Sidepak is in Survey Mode, press the "Page" button again to reach the MAIN MENU
  3. Use the arrow keys until the "Zero Cal" text appears and then press the "Enter" key, which is the angled arrow on the right side of the control panel
  4. Attach the zero calibration filter to the inlet of the Sidepak
  5. Press the Enter button again
  6. Wait 1 minute until the zeroing procedure is finished

Installing and Cleaning Sidepak Impactors

In this video, I describe the TSI Sidepak AM510 impactors and demonstrate how to clean and install them.

  1. The impactors at the inlet of the Sidepak remove particles above a specified particle size cut-off, e.g., 2.5 micrometers or 10 micrometers.
  2. The most appropriate impactor for use with monitorihng tobacco smoke is the 2.5 micrometer impactor
  3. Using the 2.5 micrometer impactor, the Sidepak can be used to monitor PM-2.5, i.e., fine particulate matter, which is regulated by the EPA and other governmental agencies
  4. The impactor head needs to be cleaned regularly
